T 0 all whom it may concern:

Be it known that I, (lAnLnfroN ELLIS, a citizen of the United States, and resident of Larchmont, county of l/Vestchester, and State of New York, have made-a certain new and useful Invention in Finish-Removers and Processes of Making the Same, of which the following is a specification.

This invention relates to finish removers and processes of making the same, and relates especially to removers prepared by the solution of a suitable acetate in alcohol or similar finish solvent material and the incorporation therewith of a suitable'waxy body dissolved in a solvent therefor, sullieient acid being preferably added to the mixture to substantially neutralize the free alkali displaced from the acetate by esteriiication of the alcohol. I

Acetates, such as metallic acetates including potassium, ammonium, sodium, magnesium and barium acetates, are quite soluble in methyl, ethyl and other alcohols and in other allied loosening finish solvent materials (that is, solvents of a generally alcoholic character or action in removers) such as the allied ketonic solvents, including methyl ethyl ketone, methyl acetone (that is, a composition containin about 40% of acetone, some wood alcoho and the balance higher ketones) and acetone. The solution may be readily effected by heating the alcoholic or similar solvent body in a reflux condenser in contact with an excess of the desired acetate or other salt capable of effecting esterification, the temperature being carried up to near the boiling point of the solvents used, or, if desired, the solution may take place in a digester preferably in the presence of an excess of the acetate, the pressure and temperature being carried up to any desired point to facilitate solution and the resulting esterification, although such increase of temperature is not always necessary to effect the desired conversion of the solvent material. In such a solution the alcohol, for instance, combines with the salt to form an ester and the base with which the acetic or other acid radical was combined is displaced to the corresponding extent, so that acetic or other esters are present in removers of this character and may add to the finish softening and solvent action thereof. Among other salts capable terial in the finish remover.

of effecting such esterification are other alcohol soluble salts preferably having organic acid radicals of the fatty or aromatic series, such as formatcs, propionates, butyrates, and so forth.

As an illustrative example, a suitable remover may be prepared by dissolving ten to twenty parts of potassium acetate in one hundred parts of methyl alcohol or in finish solvent material comprising a plurality of solvents, such, for example, as the composite solvent known as methyl acetone, in dissolving three parts of ceresin or other waxy or soapy material in one hundred parts of benzol or other wax solvent miscible with the alcoholic body and mixing the two solutions and gradually adding sufiicient strong sulfuric acid while the mixture is thoroughly agitated in a suitable emulsifier or otherwise to substantially neutralize the alkalinity due to the esterification of the alcohol. This action gives a precipitation of sodium sulfate, the particles of which are agglomerated with the colloidal waxy material thrown down at the same time so as to give a very desirable stiffening material throughout the body of the remover.

Instead of the potassium acetate referred to five to ten parts of sodium or ammonium acetate may be used and other enetrating finish solvent material, that is, finish solvents having generally benzolic character or action in removers may be used in place of the benzol such penetrating solvents comprising toluol, xylol and other homologues, naphtha, benzene and other petroleum hydrocarbons, as well as turpentine, wood turpentine, terpineol, carbon tetrachlorid and other chlorinated solvents.

Another illustrative remover may be prepared by forming a saturated solution of calcined sodium acetate in wood alcohol and similarly adding a substantially equal volume of benzol which forms a flaky precipitate. If desired, paraflin or ceresm wax may be first dissolved in the benzol so as to give two or three percent. of this Waxy ma- This, of course, gives an alkaline remover because of the presence of the displaced basic material and if desired a neutral remover may be prepared by the addition of the desired amount of suitable acid material, such as strong suli'urie or hydrochloric acid which may be incorporated by percolation of the dry acid gas, if desired.

This invention has been described in connection with a number of illustrative ingredients, formulas and proportions, to the details of which the invention is not, of course, to be limited.
